Manage E-Lines
Use the Manage E-Line tool to review and manage E-Lines.
At realization, the finite element entities at each evaluation point will be created. You can also review and edit all E-Lines in bulk in the Review E-Line dialog.
- Realize and Edit E-Lines
- Realize, review, and update interface parameters for one E-Line at a time.
- Review E-Line Table
- Use the Review E-Line dialog to review, edit, and update parameters for all E-Lines and to map material compatibility data to squeak lines.
Realize and Edit E-Lines
Review, edit, and update interface parameters for one E-Line at a time.
Review E-Lines
Use the Review E-Line dialog to review, edit, and update parameters for all E-Lines and map material compatibility data to squeak lines.
- View all E-Lines in a model.
- Edit and update E-Line parameters for single or multiple E-Lines (see Manage E-Lines Options).
- Review and update gap and tolerance values for interfaces or map interface names from an imported DTS file.
- Map materials to squeak E-Lines.
Map Materials
To map materials, you can use the existing template materials or extract information from Ziegler PEM Material Database.
Existing template materials and information from the Ziegler PEM Material Database contain data referring to pairs of material and their compatibility. This data is obtained by stick-slip testing and is used in evaluation of the squeak simulation (Squeak Evaluation).
The idea behind mapping materials is to incorporate information coming from the material database, without interfering with the cards of existing materials of the model. You must associate materials of parts at the interfaces you want to study to materials in the database. This is done to assign stick-slip testing results to an E-Line which is then used in post-processing of the E-Lines for squeak evaluation.
Manage E-Lines Options
The following options are available in the Review E-Line dialog.
- Status
- Contains the E-Lines realization status
- E-Lines ID
- A unique ID for each E-Line along with the number of connections for respective E-Lines (last digits).
- Type
- Defines what type of phenomena to evaluate along the line – rattle or squeak.
- Interface Name
- Enter a name or assign from imported DTS file (if used) to respective E-Line in model to map the GD&T data.
- Gap
- Gap value for the interface in the specified gap direction. This is defined based on the Gap assignment method.
- Tolerance
- Design tolerance for gap in the specified gap direction. This is defined based on the Gap Assignment method.
- (Impulse Rate)⁻¹ range
- Inverse of Impulse Rate range is a measure of the material pair compatibility. This is defined based on the material mapping and only applies to Squeak lines.
- Contact Type
- Define Contact type for the E-line. This is based on Youngs' modulus value of the Main and Secondary FE material.
- Gap Direction
- Realization Projection direction that controls creation of the local coordinate systems which determines the Gap direction.
- Spacing
- Value for the spacing between two adjacent Evaluation Points on an E-Line.
- Search Distance
- Value for search / gap tolerance between the selected Main-Secondary component.
- Main FE Material
- Assigned FE material for main component in the E-Line.
- Secondary FE Material
- Assigned FE material for secondary component in the E-Line.
- Main Material
- Mapped Material from Stick-Slip testing for main component in the E-Line.
- Secondary Material
- Mapped Material from Stick-Slip testing for secondary component in the E-Line.
